Patented Apr. 22, 1930 UNITED STATES PATENT 'oFFicE HAMILTON C. CHASE,013 LOS ANGELES, CALIFORITIA, ASSIG-NOR OF ONE-FOURTH TO TOBIAS WEBER AND ONE-FOURTH TO HAROLD ROE, (11? L ANGELES, CALIFORNIA VALVE Applicationfiled October 21, 1926. Serial No. 143,039.

This invention relates to a valve structure comprising a hollow shellslidably mounted within a body. The present invention per-' tains moreparticularly to a split shell struc 5 ture arranged so that pressure offiuidtherei to provide a valve structure of the character describedwhich may be operable at will and may be arranged to do'away with theneoessity of packing. These objects together with other objects andcorresponding accomplishments are obtained by means of the embodiment ofmy invention illustrated in the accompanying drawing, in which:

Fig. l is an axial section through a tank faucet embodying myimprovedvalve; Fig. 2 is a section as seen on the line 22 of Fig. 1;

and Fig. 3 is a section transverse to that of Fig. 1 taken through thevalve operating housing.

Referring more particularly to Fig. 1, a valve body is indicated by 5.This body is substantially cylindricalin form and has a spout 6depending therefrom at an angle. 0n the spout is a book 7 for engagementwith the bail of a bucket or like receptacle. The bore of the body issubstantially cylindrical, there being a port 8 at one end forcommunication -of the spout and the bore. The diameter of the bore isreduced at one end and the body is internally threaded as indicated by9. This is for the purpose of connecting a faucet to a source of supplyof liquid, such as a tank. The opposite end of the body is internallythreaded to receive a closure plug 10. At the top of the body andopposite to the spout is a slot 11 to accommodate a pin forming aportion of the operating mechanism.

Snugly fitted within the bore of the body so as to be slidablelongitudinally is a split shell 12. This shell is of such length that itmay be moved to abut the end 9- of the body and will uncover the port 8.It is split longitudinally as indicated by 13 and is provided with aninwardlyextending boss 14 providing a socket for the operating pin. Itwill be noted that the ends of the shells are bevelled.

This aids in a cleaning action on the wall against which the shell fits.

Seated on the body 5 is a housing 15 for the operatin mechanism. Thehousing is in plan in the Iorm of a sector, there being a post 16pivotally mounted in the body at one end. This post is disposed in asocket within the body and mounted below the post is a compressionspring 17. The construction is such that the post 16 may not onlyber-otated, but may be moved axially. The upper end of the post whichprojects beyond the body and is disposed within a cup-like portion issquared or flattened upon one side to provide for engagement by a keyfor turning'the post. Fixed to the post is an operating arm 19 slottedat one end to embrace an operating pin 20 disposed in socket 14.Obviously, by turning the post 16, the arm 19 may be swung and the shell12 moved within the body through the intermediate section of pin 20.Depending from the upper wall of the housing is a'lug :21 arranged toengage in the slot in the end of arm 19. This'lug is disposed so thatwhen the arm 19 is in its valve closing position, the lug will hold thearm 19 from being swung, unless the arm is moved downwardly to clear thelug. In order to swing the valve to open position it is necessary toengage the post 16, move the latter downwardly to clear the lug. Inorder to swing the arm 19 to the opposite side of the housing. I

It will be noted that the fluid to be controlled passes through thesupply end of the body into the bore of the shell. The pres sure of thefluid upon the shell causes the latter to expand and snugly fit againstthe wall of the body. No packing is required. It is obvious that theinvention may be embodied in other types of valves.

lVhat I claim is:

1. In a valve, a body having a bore with an inlet for the supply offluid thereto at one end and a discharge port in the side wall of saidbore remote from said inlet, an open ended split shell having a chamberfreely communicating with said inlet at one of its ends, said shellbeing disposed intermediate said inlet and discharge port for sliding 00movement in said bore with the other end of said shell disposed totraverse said port so as to be moved to cover and uncover said port.

2. In a valve, a body having a cylindrical bore closed at one end andopen at the other end and adapt-ed to be connected at said other end toa source of fluid supply, a discharge port in the Wall of said bore, anopen ended split shell having a passage extending therethrough with oneend facing the open end of said body and the other end disposed at saidport, said shell being disposed for sliding movement in said bore withsaid other end disposed to be moved to cover and uncover said port.

- 3. In a valve, a body having a cylindrical bore closed at one end andopen at the other end for connection to a source of fluid supply, adischarge port in the wall of said bore, an open ended split shellhaving a passage exd ng the ethro g with one n facing the open end ofsaid body and the other end disposed at said port, said shell beingdisposed for sliding movement in said bore with said other end disposedto be moved to cover and uncover said, port, a slot in the side wall ofsaid body, and operating means accommodated in said SlOVand engaged withsaid hell fo operating th e 4:. In a valve, a body having a bore with aninlet for the supply of fiuidthereto at one a and a dischar e port inthe side wall of said bore remotefrorn said inlet, an open ended splitshell having a passage extending therethrough frfiely communicating withsaid i l t a one of it e ds, ai el ng posed for sliding movement in saidbody with the other end of said shell disposed to traverse said port sovas to be moved to cover and un- CQVQI said port, there being a slot insaid body sealed by a d he l, a d, p r i g means extending through saidslot and engaged with said shell for sliding the latter.
